Definitions
- the disclosure relates to a rotary operator and an acoustic device.
- a variable resistor has been conventionally known in which a resistance value is changed by rotating a shaft (see, for example, Patent Literature 1).
- Patent Literature 2 There is also known a container of a switch that locks an operation handle rotated to an on-operation position (see, for example, Patent Literature 2).
- the container described in Patent Literature 2 includes a stopper piece in addition to the operation handle.
- the stopper piece restricts rotation of the operation handle when the operation handle is rotated to the on-position, and locks the operation handle at the on-position.
- the stopper piece releases the operation handle from the locked state if the operation handle is pushed in while the operation handle is in the locked state.
- a variable resistor described in Patent Literature 1 may be employable as a rotary operator that adjusts an effect amount of a first effect, for example, by rotating a shaft clockwise with respect to a reference position and that adjusts an effect amount of a second effect different from the first effect, for example, by rotating counterclockwise.
- the shaft passes the reference position with no resistance. This may cause a case where the shaft accidentally passes the reference position when the shaft is rotated clockwise or counterclockwise to adjust, for example, the effect amount of the first effect.
- variable resistor when the variable resistor is configured such that the shaft is to be locked at the reference position by reference to a container described in Patent Literature 2, an operation handle needs to be pushed in to release the lock, which is inconvenient to use.

- the contact piece 51 is thus movable beyond the path forming portion 47 in a direction from the first position toward the second position, i.e., in the ⁇ Z direction.
- the contact portion 515 moves in the ⁇ Z direction owing to the biasing force of the first biasing member 52 and returns to the bottom 461 . That is, the contact piece 51 returns to the second position.
- the contact portion 515 moves relatively in the ⁇ D direction with respect to the rotator 42 along the inclined portion 463 , and moves relatively with respect to the rotator 42 along the first path RT 21 and the second path RT 22 .
- the restricting portion 471 restricts the rotation in the ⁇ D direction of the rotator 42 .
- the position of the contact piece 51 when the contact portion 515 comes into contact with the restricting portion 471 is the first position in the clockwise-side range described above.
- the contact piece 51 moves in the +Y direction as the contact piece 51 moves in the +D direction along the guide surface 473 .
- the contact piece 51 is movable beyond the path forming portion 47 from the first position to the second position.
- the contact piece 51 moves in the +Y direction as the contact piece 51 moves in the ⁇ D direction along the guide surface 483 .
- the contact piece 51 is movable beyond the path forming portion 48 from the first position to the second position.

- FIG. 15 illustrates a cross section of the rotary operator 2 taken along a line XV-XV indicated in FIG. 5 .
- the contact piece 51 is disposed at the second position.
- the contact piece 51 is pushed out in the +Y direction by the guide surface 473 , and is simultaneously pressed against an inner surface 343 A provided in the +X direction of the guide hole 343 as illustrated in FIG. 15 . Further, upon the rotation in the ⁇ D direction of the rotator 42 in the clockwise-side range, the contact piece 51 is pushed out in the +Y direction by the guide surface 483 , and is simultaneously pressed against an inner surface 343 B provided in the ⁇ X direction of the guide hole 343 .
- the contact portion 515 is thus in a state of being caught between the guide surface 473 and the inner surface 3438 , or in a state of being caught between the guide surface 483 and the inner surface 343 A. In this case, it is difficult for the contact piece 51 to move from the first position to the second position.
- Whether or not the contact piece 51 moves to the second position while being pushed out in the +Y direction by the guide surface 473 or the guide surface 483 depends on a balance between the biasing force of the first biasing member 52 and the biasing force of the second biasing member 53 .
- setting the biasing force of the first biasing member 52 to be lower than a first threshold and setting the biasing force of the second biasing member 53 to be higher than a second threshold make it possible to configure the rotary operator 2 such that no movement toward the second position is generated during the rotation of the rotator 42 , i.e., when a torque that makes the rotator 42 rotatable is applied to the knob 43 .
- setting the biasing force of the first biasing member 52 to be higher than the first threshold and setting the biasing force of the second biasing member 53 to be lower than the second threshold make it possible to configure the rotary operator 2 such that the contact piece 51 reaches the second position prior to reaching the restricting surface 472 or the restricting surface 482 , unless the rotator 42 is rotated above a predetermined rotation rate.
- the rotary operator 2 can be configured such that: the restricting surface 472 does not restrict the movement of the contact piece 51 in the +D direction, i.e., the rotation of the rotator 42 in the ⁇ D direction; and the restricting surface 482 does not restrict the movement of the contact piece 51 in the ⁇ D direction, i.e., the rotation of the rotator 42 in the +D direction.

In other words, the protrusion 614 has an inclined surface facing the +D direction and an inclined surface facing the ⁇ D direction.
- the protrusion 614 fits into the fitting portion 451 when the rotator 42 is rotated to generate the clicking feeling.
- a position of the fitting portion 451 in the rotator 42 and a position of the protrusion 614 in the click plate 61 are defined such that the clicking feeling occurs when, for example, the rotator 42 is disposed at a first reference position.
- the click plate 61 is movable in the ⁇ Z directions.

More specifically, the inclined portion 624 is inclined to face the +Z direction and the counterclockwise direction about the rotation axis Rx as viewed from the +Z direction.
- the inclined portion 624 pushes up in the +Z direction the engagement portion 613 and the to-be-guided portion 612 in the ⁇ X direction in association with the counterclockwise rotation as viewed from the +Z direction of the movement base 62 , and thus separates the click plate 61 from the cylindrical portion 45 .

- the click plate 61 When the click plate 61 is not moved in the +Z direction by the movement base 62 , the click plate 61 is biased by the biasing member 63 in the direction toward the cylindrical portion 45 of the rotating body 44 , and is disposed at a position where the protrusion 614 is fittable in the fitting portion 451 in the +Z direction. That is, the click plate 61 is disposed at a position at which the clicking feeling can occur.
- the protrusion 614 is separated in the +Z direction from the fitting portion 451 .

- the click plate 61 of the operational-feeling switching mechanism 6 is disposed at a position at which the protrusion 614 is fittable in the fitting portion 451 by the movement base 62 .

Accordingly, the holding member 54 is biased in the ⁇ Y direction by the second biasing member 53 , and the contact piece 51 is thus biased toward the rotation axis Rx. This causes the contact portion 515 to come into contact with the rotator 42 . The contact portion 515 moves along the movement paths RT 1 and RT 2 in association with the rotation of the rotator 42 , and the rotation of the rotator 42 that passes the reference position is restricted.

Abstract
A rotary operator includes: a rotator including a movement path provided for an outer circumferential surface and inclined to a circumferential direction about a rotation axis, the rotator rotating about the axis; and a contact piece coming into contact with the rotator, and moving along the path in a direction along the axis in association with rotation of the rotator. Rotation of the rotator in a first rotation direction is restricted by the contact piece being at a first position when the rotator reaches a predetermined position. When rotating force applied to the rotator is reduced in a state where rotation of the rotator in the first rotation direction from the predetermined position is restricted, the contact piece returns to a second position to allow the rotation of the rotator in the first rotation direction from the predetermined position.

The stopper piece restricts rotation of the operation handle when the operation handle is rotated to the on-position, and locks the operation handle at the on-position. The stopper piece releases the operation handle from the locked state if the operation handle is pushed in while the operation handle is in the locked state. - This prevents, when performing an on-operation on the operation handle, the operation handle from continuing to be rotated in an off-direction after passing the on-position, and prevents the operation handle from being rotated to an off-position.

- Patent Literature 2: JP 2005-100856 A
- In an acoustic device, a variable resistor described in
Patent Literature 1 may be employable as a rotary operator that adjusts an effect amount of a first effect, for example, by rotating a shaft clockwise with respect to a reference position and that adjusts an effect amount of a second effect different from the first effect, for example, by rotating counterclockwise. - However, in the variable resistor described in
Patent Literature 1, the shaft passes the reference position with no resistance. This may cause a case where the shaft accidentally passes the reference position when the shaft is rotated clockwise or counterclockwise to adjust, for example, the effect amount of the first effect. - In contrast, when the variable resistor is configured such that the shaft is to be locked at the reference position by reference to a container described in
Patent Literature 2, an operation handle needs to be pushed in to release the lock, which is inconvenient to use. - Thus, there is a demand for a rotary operator that improves operability.
- An object of the disclosure is to solve at least some of the above-described issues. It is one of the objects of the disclosure to provide a rotary operator with improved operability.
- A rotary operator according to a first aspect of the disclosure includes: a rotator including a movement path provided for an outer circumferential surface and inclined to a circumferential direction about a rotation axis, the rotator being configured to rotate about the rotation axis; and a contact piece configured to come into contact with the rotator, and move along the movement path in a direction along the rotation axis in association with rotation of the rotator, in which rotation of the rotator in a first rotation direction about the rotation axis is restricted by the contact piece being at a first position when the rotator is rotated in the first rotation direction and reaches a predetermined position; and when rotating force in the first rotation direction applied to the rotator is reduced in a state where rotation of the rotator in the first rotation direction from the predetermined position is restricted, the contact piece returns to a second position to allow the rotation of the rotator in the first rotation direction from the predetermined position.
- An acoustic device according to a second aspect of the disclosure includes the above rotary operator.

As illustrated inFIG. 5 , when a position of therotator 42 with the indicatingline 431 being parallel to the −X direction and being directed to the −X direction is set as a reference position, therotator 42 is configured to be rotatable clockwise substantially 150° from the reference position, for example, and rotatable counterclockwise substantially 150° from the reference position, for example. That is, the reference position is a position at which a range from the reference position to a position where the clockwise rotation of therotator 42 about the rotation axis Rx is allowed as viewed from the +Z direction is equal in length to a range from the reference position to a position where the counterclockwise rotation of therotator 42 about the rotation axis Rx is allowed as viewed from the +Z direction. In other words, the reference position is a position at which a rotation range from the reference position to a clockwise rotation limit is equal in length to a rotation range from the reference position to a counterclockwise rotation limit. The reference position corresponds to a predetermined position according to the disclosure. - In the following explanation, a clockwise direction viewed from the +Z direction is set as a +D direction, and a counterclockwise direction viewed from the +Z direction is set as a −D direction.
- The rotating
body 44 includes acylindrical portion 45 having a cylindrical shape about the rotation axis Rx. - The
cylindrical portion 45 includes afitting portion 451 on the plane in the +Z direction. In thefitting portion 451, a protrusion 614 (see,FIG. 17 ) to be described later provided in theclick plate 61 is fitted in association with the rotation of therotator 42. - The
cylindrical portion 45 includes, on an outercircumferential surface 45A about the rotation axis Rx: arecess 46 recessed in a direction toward the rotation axis Rx from the outercircumferential surface 45A; andpath forming portions circumferential surface 45A. -
FIG. 8 is a side view of therotator 42 viewed from the +Y direction. - The
contact piece 51 is fitted into therecess 46 when therotator 42 is located at the reference position. Therecess 46 is provided at a center portion in the +Z direction of thecylindrical portion 45. Therecess 46 has a bottom 461 andinclined portions - The bottom 461 is a flat part that is located nearest to the rotation axis Rx in the
recess 46. The contact portion 515 (see,FIGS. 9 and 10 ) that comes into contact with the outercircumferential surface 45A of thecontact piece 51 is optionally disposed on the bottom 461. - The
inclined portion 462 is disposed in the +D direction with respect to the bottom 461. Theinclined portion 462 is inclined to be separated from the rotation axis Rx toward the +D direction. That is, theinclined portion 462 is inclined to be located radially outward about the rotation axis Rx toward the +D direction. When therotator 42 is rotated in the −D direction, theinclined portion 462 leads, to a first path RT11 of thepath forming portion 47, thecontact portion 515 that moves relatively in the +D direction with respect to therotator 42. - The
inclined portion 463 is disposed in the −D direction with respect to the bottom 461. Theinclined portion 463 is inclined to be separated from the rotation axis Rx toward the −D direction. That is, theinclined portion 463 is inclined to be located radially outward about the rotation axis Rx toward the −D direction. When therotator 42 is rotated in the +D direction, theinclined portion 463 leads, to a first path RT21 of thepath forming portion 48, the contact portion that moves relatively in the −D direction with respect to therotator 42. - The
path forming portions circumferential surface 45A. Thepath forming portions FIGS. 9 and 10 ) when therotator 42 is rotated. That is, therotator 42 has a cylindrical cam structure in which the movement paths RT1 and RT2 are provided. The movement paths RT1 and RT2 are each inclined to a circumferential direction about the rotation axis Rx, and each allow thecontact piece 51 to move along the rotation axis Rx in accordance with the rotation of therotator 42. - As illustrated in
FIGS. 7 and 8 , thepath forming portions recess 46. - The
path forming portion 47 forms the movement path RT1 of thecontact portion 515 when therotator 42 is rotated in a rotation range from the reference position to the rotation limit in the −D direction. Thepath forming portion 47 is provided continuously with theinclined portion 462. Thepath forming portion 47 comes into contact with a part in the −Z direction of thecontact portion 515. - Hereinafter, the rotation range from the reference position to the rotation limit in the −D direction is referred to as a counterclockwise-side range of the
rotator 42. Further, the rotation range from the reference position to the rotation limit in the +D direction is referred to as a clockwise-side range of therotator 42. - The movement path RT1 includes the first path RT11 and a second path RT12.
- The first path RT11 is provided continuously with the
inclined portion 462 of therecess 46. The first path RT11 is inclined to be located in the +Z direction toward the +D direction. That is, the first path RT11 is inclined to the circumferential direction about the rotation axis Rx. An end in the +D direction of the first path RT11 is connected to the second path RT12. Thus, when therotator 42 is rotated in the −D direction, thecontact portion 515 moves in the +D direction along the first path RT11 to reach the second path RT12. - The second path RT12 is a path that is inclined to the circumferential direction about the rotation axis Rx to be located in the −Z direction toward the +D direction. The second path RT12 is longer in the +D direction than the first path RT11. That is, the second path RT12 is inclined to the circumferential direction about the rotation axis Rx. When the
rotator 42 is most rotated in the −D direction, thecontact portion 515 moves further in the +D direction beyond the second path RT12. A position in the +Z direction of thecontact piece 51 at this time is the same as a position in the +Z direction of thecontact piece 51 when thecontact portion 515 is disposed on the bottom 461 owing to biasing force of a first biasingmember 52 to be described later. - Further, an end in the +D direction of the
path forming portion 47 is disposed in the −Z direction relative to an end in the −Z direction of thecontact portion 515 when the rotation axis Rx is set as the center and thecontact piece 51 is disposed at a second position. Thus, when therotator 42 is most rotated in the −D direction and is thereafter rotated in the +D direction, thecontact portion 515 comes into contact with a surface in the +Z direction of thepath forming portion 47 and is moved along the second path RT12. However, the disclosure is not limited thereto, and when therotator 42 is most rotated in the −D direction, thecontact portion 515 may be disposed at a predetermined part in the second path RT12. - The second path RT12 is provided radially inward about the rotation axis Rx relative to the first path RT11. That is, the second path RT12 is provided at a position closer to the rotation axis Rx than the first path RT11.
- When the
rotator 42 is rotated in the +D direction in the counterclockwise-side range, the second path RT12 leads thecontact portion 515 moving in the −D direction to a restrictingportion 481 of thepath forming portion 48. - The
path forming portion 48 forms a movement path RT2 of thecontact portion 515 when therotator 42 is rotated in a rotation range from the reference position to the rotation limit in the +D direction. Thepath forming portion 48 is provided continuously with theinclined portion 463. Thepath forming portion 48 comes into contact with a part in the +Z direction of thecontact portion 515. - Hereinafter, a range from the reference position to the rotation limit in the +D direction of the
rotator 42 is referred to as a clockwise-side range of therotator 42. - The movement path RT2 includes the first path RT21 and a second path RT22.
- The first path RT21 is provided continuously with the
inclined portion 463 of therecess 46. The first path RT21 is inclined to be located in the −Z direction toward the −D direction. That is, the first path RT21 is inclined to the circumferential direction about the rotation axis Rx. An end in the −D direction of the first path RT21 is connected to the second path RT22. Thus, when therotator 42 is rotated in the +D direction, thecontact portion 515 moves in the −D direction along the first path RT21 to reach the second path RT22. The first path RT21 is provided radially outward about the rotation axis Rx relative to the second path RT22. - The second path RT22 is a path that is inclined to the circumferential direction about the rotation axis Rx to be located in the +Z direction toward the −D direction. The second path RT22 is longer in the −D direction than the first path RT21. When the
rotator 42 is most rotated in the +D direction, thecontact portion 515 moves further in the −D direction beyond the second path RT22. A position in the +Z direction of thecontact piece 51 at this time is the same as a position when thecontact piece 51 is disposed at the second position owing to the biasing force of the first biasingmember 52 to be described later. Further, an end in the −D direction of thepath forming portion 48 is disposed in the −Z direction relative to an end in the +Z direction of thecontact portion 515 that has the rotation axis Rx as its center and disposed at the second position. Thus, when therotator 42 is most rotated in the +D direction and is thereafter rotated in the −D direction, thecontact portion 515 comes into contact with a surface in the −Z direction of thepath forming portion 48 and is moved along the second path RT22. However, the disclosure is not limited thereto, and when therotator 42 is most rotated in the +D direction, thecontact portion 515 may be disposed at a predetermined part in the second path RT22. - When the
rotator 42 is rotated in the −D direction in the clockwise-side range, the second path RT22 leads thecontact portion 515 moving in the +D direction to the restrictingportion 471 of thepath forming portion 47. - The
path forming portion 47 further includes the restrictingportion 471 provided at an end in the −D direction of thepath forming portion 47. The restrictingportion 471 is provided in the −Z direction with respect to therecess 46. - The restricting
portion 471 includes a restrictingsurface 472 and aguide surface 473. - The restricting
surface 472 is substantially perpendicular to the circumferential direction about the rotation axis Rx. When therotator 42 is rotated in the −D direction and reaches the reference position in the clockwise-side range of therotator 42, thecontact piece 51 moved relatively in the +D direction with respect to therotator 42 comes into contact with the restrictingsurface 472. This allows the restrictingportion 471 to restrict thecontact piece 51 from further moving in the +D direction and to restrict therotator 42 from rotating in the −D direction from the reference position. A position of thecontact piece 51 when thecontact portion 515 is brought into contact with the restrictingportion 471 is defined as a first position in the clockwise-side range of therotator 42. The first position in the clockwise-side range is in the −Z direction relative to a position of thecontact piece 51 when thecontact portion 515 is disposed on the bottom 461. The position of thecontact piece 51 when thecontact portion 515 is disposed on the bottom 461 is defined as the second position. - The
guide surface 473 guides, to the restrictingsurface 472, thecontact piece 51 moved along the movement path RT2 formed by thepath forming portion 48 and the outercircumferential surface 45A. Theguide surface 473 includes afirst guide surface 474 and asecond guide surface 475. - The
first guide surface 474 is continuous with the second path RT22 and the outercircumferential surface 45A. Thefirst guide surface 474 intersects the circumferential direction about the rotation axis Rx to be located radially outward about the rotation axis Rx toward the +D direction. - The
second guide surface 475, which is provided between thefirst guide surface 474 and the restrictingsurface 472, is continuous with thefirst guide surface 474 and the restrictingsurface 472. Thesecond guide surface 475 intersects the circumferential direction about the rotation axis Rx to be located radially outward about the rotation axis Rx toward the +D direction. An inclination angle of thesecond guide surface 475 with respect to the circumferential direction about the rotation axis Rx is greater than an inclination angle of thefirst guide surface 474 with respect to the circumferential direction. - The
contact piece 51 that reaches theguide surface 473 from the second path RT22 further moves relatively in the +D direction with respect to therotator 42, thereby moving along theguide surface 473 in the +Y direction away from therotator 42, and also reaching a position in contact with the restrictingsurface 472. When the rotating force in the −D direction applied to therotator 42 is reduced in this state, the biasing force of the first biasingmember 52 to be described later causes thecontact portion 515 to move in the +Z direction beyond thepath forming portion 48 that forms the second path RT22, and to reach the bottom 461. That is, thecontact piece 51 reaches the second position. - As with the
path forming portion 47, thepath forming portion 48 further includes the restrictingportion 481 provided at an end in the +D direction of thepath forming portion 48. The restrictingportion 481 is provided in the +Z direction with respect to therecess 46. - The restricting
portion 481 includes a restrictingsurface 482 and aguide surface 483. - The restricting
surface 482 is substantially perpendicular to the circumferential direction about the rotation axis Rx. When therotator 42 is rotated in the +D direction and reaches the reference position in the counterclockwise-side range of therotator 42, thecontact piece 51 moved relatively in the −D direction with respect to therotator 42 comes into contact with the restrictingsurface 482. This allows the restrictingportion 481 to restrict thecontact piece 51 from further moving in the −D direction and to restrict therotator 42 from rotating in the +D direction from the reference position. A position of thecontact piece 51 when thecontact portion 515 is brought into contact with the restrictingportion 481 is defined as a first position in the counterclockwise-side range of therotator 42. The first position in the counterclockwise-side range is in the +Z direction with respect to the second position. - As with the
guide surface 473, theguide surface 483 guides, to the restrictingsurface 482, thecontact piece 51 moved along the movement path RT1 formed by thepath forming portion 47 and the outercircumferential surface 45A. - The
guide surface 483 includes afirst guide surface 484 and asecond guide surface 485. - The
first guide surface 484 is continuous with the second path RT22 and the outercircumferential surface 45A. Thefirst guide surface 484 intersects the circumferential direction about the rotation axis Rx to be located radially outward about the rotation axis Rx toward the −D direction. - The
second guide surface 485, which is provided between thefirst guide surface 484 and the restrictingsurface 482, is continuous with thefirst guide surface 484 and the restrictingsurface 482. Thesecond guide surface 485 intersects the circumferential direction about the rotation axis Rx to be located radially outward about the rotation axis Rx toward the +D direction. An inclination angle of thesecond guide surface 485 with respect to the circumferential direction about the rotation axis Rx is greater than an inclination angle of thefirst guide surface 484 with respect to the circumferential direction. - The
contact piece 51 that reaches theguide surface 483 from the second path RT12 further moves relatively in the −D direction with respect to therotator 42, thereby moving along theguide surface 483 in the +Y direction away from therotator 42, and also reaching a position in contact with a restricting surface 481A. When the rotating force in the +D direction applied to therotator 42 is reduced in this state, the biasing force of the first biasingmember 52 to be described later causes thecontact portion 515 to move in the −Z direction beyond thepath forming portion 47 that forms the second path RT12, and to reach the bottom 461. That is, thecontact piece 51 reaches the second position. - As described above, the movement paths RT1 and RT2 are provided for the outer
circumferential surface 45A of therotator 42. The movement paths RT1 and RT2 are each inclined to the circumferential direction about the rotation axis Rx. Therotator 42 is rotated about the rotation axis Rx. Thecontact portion 515 that moves along the movement paths RT1 and RT2 will be described in detail later. - Configuration of Restriction Switching Mechanism
FIG. 9 is a perspective view of therestriction switching mechanism 5, andFIG. 10 is a plan view of therestriction switching mechanism 5 viewed from the +Z direction. It is to be noted thatFIGS. 9 and 10 each illustrate therestriction switching mechanism 5 engaged with theoperator body 4. - In response to the switching operation on the
state switching mechanism 7, therestriction switching mechanism 5 performs switching between a restricted state where the rotation of therotator 42 is restricted by the restrictingportions rotator 42 is not restricted. That is, therestriction switching mechanism 5 performs switching between the restricted state where the rotation of therotator 42 is restricted at the reference position and the unrestricted state where the rotation of therotator 42 is not restricted at the reference position. - As illustrated in
FIGS. 9 and 10 , therestriction switching mechanism 5 includes thecontact piece 51, the first biasingmember 52, the second biasingmember 53, the holdingmember 54, the switchingmember 55, and the third biasingmember 56. - Configuration of Contact Piece
FIG. 11 is an exploded perspective view of therestriction switching mechanism 5 viewed from the +X direction and the −Y direction.FIG. 12 is an exploded perspective view of therestriction switching mechanism 5 viewed from the −X direction and the +Y direction. InFIGS. 11 and 12 , illustrations of the switchingmember 55 and the third biasingmember 56 are omitted. - The
contact piece 51, which is provided to be accessible to therotator 42, comes into contact with the restrictingportions rotator 42. Thecontact piece 51 moves relatively in the ±D directions with respect to therotator 42 along the movement paths RT1 and RT2, in association with the rotation of therotator 42. Further, thecontact piece 51 moves in the ±Z directions along the movement paths RT1 and RT2, in association with the rotation of therotator 42. The +Z direction and the −Z direction are each a direction along the rotation axis Rx. - As illustrated in
FIGS. 11 and 12 , thecontact piece 51 has a substantially cross shape as viewed from the +X direction. Thecontact piece 51 includes acontact piece body 511, thecontact portion 515, and aprotrusion 516. - The
contact piece body 511 has a substantially rectangular shape as viewed from the +X direction or the −X direction. As illustrated inFIG. 12 , thecontact piece body 511 includes anarrangement portion 512 having a substantially rectangular shape that is long in the +Y direction, and to-be-inserted portions arrangement portion 512. - The
arrangement portion 512 is a recess that is open in the −X direction. - When the
contact piece 51 and the holdingmember 54 are combined, the first biasingmember 52 included in the holdingmember 54 is disposed inside thearrangement portion 512. - The to-
be-inserted portion 513 is provided in the +Z direction with respect to thearrangement portion 512. The to-be-inserted portion 513 is open in the −X direction and also in the +Z direction, and is provided continuously with thearrangement portion 512. Into the to-be-inserted portion 513, afirst locking portion 5432 of the holdingmember 54 is to be inserted. - The to-
be-inserted portion 514 is provided in the −Z direction with respect to thearrangement portion 512. The to-be-inserted portion 514 is open in the −X direction and also in the −Z direction, and is provided continuously with thearrangement portion 512. Into the to-be-inserted portion 514, asecond locking portion 5434 of the holdingmember 54 is to be inserted. - The
contact portion 515 is a substantially quadrangular prism-shaped part protruding from thecontact piece body 511 in the −Y direction. Thecontact portion 515 is inserted through the guide hole 343 (seeFIG. 5 ) provided in thecasing 3 and comes into contact with the outercircumferential surface 45A of therotator 42. That is, an end surface in the −Y direction of thecontact portion 515 is a contact surface of thecontact piece 51 that is accessible to the outercircumferential surface 45A. - The
protrusion 516 is a substantially quadrangular prism-shaped part protruding from thecontact piece body 511 in the +Y direction. Theprotrusion 516 is inserted through the guide 344 (see,FIG. 5 ) provided in thecasing 3 along the +Y direction. Thecontact portion 515 is inserted through theguide hole 343 and theprotrusion 516 is inserted through theguide 344, which restricts thecontact piece 51 from rotating together with therotator 42, and moves thecontact piece 51 in the +Z direction or the −Z direction in association with the rotation of therotator 42. - Configuration of First Biasing Member
- As illustrated in
FIG. 11 , the first biasingmember 52 is provided in the holdingmember 54. Thefirst biasing member 52 biases thecontact piece 51 in the +Z direction and the −Z direction to maintain thecontact piece 51 at the same position as the second position in the +Z direction. More specifically, when thecontact portion 515 is located in the +Z direction relative to therecess 46, the first biasingmember 52 biases thecontact piece 51 in the −Z direction. When thecontact portion 515 is located in the −Z direction relative to therecess 46, the first biasingmember 52 biases thecontact piece 51 in the +Z direction. That is, the first biasingmember 52 biases thecontact piece 51 in the −Z direction that is a direction from the first position toward the second position in the counterclockwise-side range, and also biases thecontact piece 51 in the +Z direction that is a direction from the first position toward the second position in the clockwise-side range. - In the exemplary embodiment, the first biasing
member 52 is in a form of a compression coil spring. - Configuration of Second Biasing Member
- As illustrated in
FIG. 12 , the second biasingmember 53 is provided in the holdingmember 54. Thesecond biasing member 53 biases thecontact piece 51 in the −Y direction via the holdingmember 54. That is, the second biasingmember 53 biases thecontact piece 51 in a direction toward the rotation axis Rx of therotator 42 via the holdingmember 54. - In the exemplary embodiment, the second biasing
member 53 is in a form of a compression coil spring. The end in the +Y direction of the second biasingmember 53 is held by the holding portion 341 (see,FIG. 6 ) of thecasing 3, and an end in the −Y direction of the second biasingmember 53 is held by asecond holding portion 544 of the holdingmember 54. - Configuration of Holding Member
- The holding
member 54 holds the first biasingmember 52 and the second biasingmember 53, and causes the biasing force of the first biasingmember 52 and the biasing force of the second biasingmember 53 to act on thecontact piece 51. Specifically, the holdingmember 54 maintains a position of thecontact piece 51 such that thecontact portion 515 is disposed at the same position as therecess 46 in the +Z direction owing to the biasing force of the first biasingmember 52. Further, the holdingmember 54 maintains a state where thecontact portion 515 is in contact with the outercircumferential surface 45A owing to the biasing force of the second biasingmember 53. - As illustrated in
FIGS. 11 and 12 , the holdingmember 54 includes afirst protrusion 541, asecond protrusion 542, afirst holding portion 543, thesecond holding portion 544, and a to-be-pressed portion 545. - The
first protrusion 541 protrudes in the +X direction from an end in the +Z direction of the holdingmember 54. On an end surface in the +X direction of thefirst protrusion 541, arecess 5411 recessed in the −X direction is provided. In therecess 5411, an unillustrated protrusion of thecasing 3 is inserted, whereby sliding of the holdingmember 54 in the ±Y directions is guided, and the holdingmember 54 is prevented from moving in the ±Z directions. - The
second protrusion 542 protrudes in the −Y direction from the end in the +Z direction of the holdingmember 54. Thesecond protrusion 542 is inserted into an unillustrated recess of thecasing 3. - The
first holding portion 543 holds the first biasingmember 52. As illustrated inFIG. 11 , thefirst holding portion 543 includes afirst holding piece 5431, thefirst locking portion 5432, asecond holding piece 5433, and thesecond locking portion 5434. - The
first holding piece 5431 and thesecond holding piece 5433 are provided in a part in the +X direction of the holdingmember 54, the holdingpieces first holding piece 5431 is separated in the +Z direction from thesecond holding piece 5433. - The
first holding piece 5431 is inserted in an end in the +Z direction of the first biasingmember 52, and thesecond holding piece 5433 is inserted in an end in the −Z direction of the first biasingmember 52. -
FIG. 13 illustrates a cross section along a YZ plane of therotator 42 and therestriction switching mechanism 5. - As illustrated in
FIG. 11 , thefirst locking portion 5432 protrudes in the +X direction from a part in the +Z direction of thefirst holding piece 5431. Thesecond locking portion 5434 protrudes in the +X direction from a part in the −Z direction of thesecond holding piece 5433. - As illustrated in
FIG. 13 , when thecontact piece 51 is moved in the +Z direction, the end in the +Z direction of the first biasingmember 52 abuts against a surface in the −Z direction of thefirst locking portion 5432, and thefirst locking portion 5432 locks the first biasingmember 52. This restricts the first biasingmember 52 from moving together with thecontact piece 51 in the +Z direction, and causes the first biasingmember 52 to generate the biasing force to bias thecontact piece 51 in the −Z direction. That is, when thecontact piece 51 moves in the +Z direction, the first biasingmember 52 biases thecontact piece 51 in the −Z direction. - When
contact piece 51 is moved in the −Z direction, the end in the −Z direction of the first biasingmember 52 abuts against a surface in the +Z direction of thesecond locking portion 5434, and thesecond locking portion 5434 locks the first biasingmember 52. This restricts the first biasingmember 52 from moving together with thecontact piece 51 in the −Z direction, and causes the first biasingmember 52 to generate the biasing force to bias thecontact piece 51 in the +Z direction. That is, when thecontact piece 51 moves in the −Z direction, the first biasingmember 52 biases thecontact piece 51 in the +Z direction. - As illustrated in
FIG. 12 , thesecond holding portion 544 holds the second biasingmember 53. Thesecond holding portion 544 includes afirst wall portion 5441 and asecond wall portion 5443 opposed to each other in the +Y direction. - The
first wall portion 5441 includes aninsertion portion 5442 to be inserted into an end in the −Y direction of the second biasingmember 53 disposed along the +Y direction. - The
second wall portion 5443 is provided in the +Y direction with respect to thefirst wall portion 5441. The holdingportion 341 of the casing 3 (see,FIG. 6 ) is disposed between thefirst wall portion 5441 and thesecond wall portion 5443 in the +Y direction. As described above, an end in the −Y direction of the holdingportion 341 locks the end in the +Y direction of the second biasingmember 53. - In this manner, the end in the −Y direction of the second biasing
member 53 is locked to thefirst wall portion 5441 in a state where the end in the +Y direction of the second biasingmember 53 is in contact with thecasing 3. Thus, the holdingmember 54 and thecontact piece 51 are biased in the Y direction by the second biasingmember 53. That is, the holdingmember 54 and thecontact piece 51 are biased by the second biasingmember 53 toward the rotation axis Rx of therotator 42. - As illustrated in
FIGS. 10 to 12 , the to-be-pressed portion 545 is provided on a surface in the −Y direction of thesecond wall portion 5443. The to-be-pressed portion 545 is pressed in the +Y direction by the switchingmember 55 rotated counterclockwise as viewed from the +Z direction. At this time, the holdingmember 54 is moved in the +Y direction against the biasing force of the second biasingmember 53, and thus thecontact piece 51 is moved in the +Y direction. As a result, it is possible to cause thecontact piece 51 to be separated from therotator 42 to such an extent that thecontact portion 515 does not come into contact with therotator 42, and to switch the state of therotator 42 to the unrestricted state where the rotation of therotator 42 is not restricted at the reference position. - Configuration of Switching Member
- The switching
member 55 switches the position of thecontact piece 51 in association with sliding of aslide member 72 to be described later, between: a position at which thecontact piece 51 is accessible to therotator 42 of therotary operator 2; and a position at which thecontact piece 51 is not accessible to therotator 42 of therotary operator 2. As illustrated inFIGS. 9 and 10 , the switchingmember 55 is a lever that is supported by the lever support 35 (see,FIGS. 5 and 6 ) of thecasing 3 such that the switchingmember 55 is rotatable clockwise and counterclockwise as viewed from the +Z direction. The switchingmember 55 rotates in association with the sliding of theslide member 72 to switch the position of thecontact piece 51. The switchingmember 55 includes apressing portion 551, anengagement portion 552, and a lockingportion 553. - The
pressing portion 551 presses the to-be-pressed portion 545 in the +Y direction to separate thecontact piece 51 from therotator 42 when the switchingmember 55 rotates counterclockwise as viewed from the +Z direction. - The
engagement portion 552 engages with theslide member 72 of thestate switching mechanism 7 to be described below. Theengagement portion 552 is provided on an end of the switchingmember 55 opposite to an end on which thepressing portion 551 is provided. Theengagement portion 552 is a cylindrical boss that protrudes in the −Z direction. - The locking
portion 553 locks an end of the third biasingmember 56. - Configuration of Third Biasing Member
- The
third biasing member 56 is the torsion coil spring provided in the lever support 35 (see,FIGS. 5 and 6 ). One end of the third biasingmember 56 is locked by the locking portion 36 (see,FIGS. 5 and 6 ) and the other end of the third biasingmember 56 is locked to the lockingportion 553 of the switchingmember 55. - The
third biasing member 56 biases the switchingmember 55 counterclockwise as viewed from the +Z direction. The switchingmember 55 rotated counterclockwise presses the holdingmember 54 in the +Y direction, and thus thecontact piece 51 is separated in the +Y direction from therotator 42, as described above. That is, the third biasingmember 56 biases thecontact piece 51 in the +Y direction away from therotator 42. - In contrast, when the
slide member 72 to be described later of thestate switching mechanism 7 is slid in the +Y direction, theslide member 72 causes the switchingmember 55 to rotate clockwise as viewed from the +Z direction against the biasing force of the third biasingmember 56. Thus, thepressing portion 551 is separated from the to-be-pressed portion 545, the holdingmember 54 and thecontact piece 51 become movable in the −Y direction owing to the biasing force of the second biasingmember 53, and thecontact portion 515 comes into contact with thecylindrical portion 45 of therotator 42. - Restriction on Rotation of Rotator by Contact Piece
FIG. 14 schematically illustrates a position of thecontact portion 515 when therotator 42 is rotated in the counterclockwise-side range. - When the
rotator 42 is located at the reference position, thecontact piece 51 is disposed at the second position where thecontact portion 515 is disposed on the bottom 461. When therotator 42 is rotated in the −D direction from the state where therotator 42 is disposed at the reference position, thecontact portion 515 reaches the first path RT11 from the bottom 461 via theinclined portion 462, as indicated by a position PS1 inFIG. 14 . - In a state where the
contact portion 515 is located on theinclined portion 462 or the first path RT11, when therotator 42 is rotated in the +D direction and thecontact portion 515 moves relatively in the −D direction, thecontact portion 515 returns to the bottom 461. - When the
rotator 42 is rotated further in the −D direction in a state where thecontact portion 515 is disposed on the first path RT11, thecontact portion 515 reaches the second path RT12 from the first path RT11, as indicated by a position PS2 inFIG. 14 , for example. At this time, the biasing force in the −Z direction by the first biasingmember 52 acts on thecontact piece 51, and thecontact portion 515 is pressed in the −Z direction against thepath forming portion 47. - When the
rotator 42 is rotated in the −D direction in a state where thecontact portion 515 is disposed on the second path RT12, thecontact portion 515 moves relatively in the +D direction with respect to therotator 42 along the second path RT12, as indicated by a position PS3 inFIG. 14 , for example. Similarly, when therotator 42 is rotated in the +D direction in the state where thecontact portion 515 is disposed on the second path RT12, thecontact portion 515 is moved relatively in the −D direction with respect to therotator 42 along the second path RT12. - At this time, when the
contact portion 515 is disposed in the +Z direction relative to the bottom 461, the first biasingmember 52 applies the biasing force in the −Z direction to thecontact portion 515. That is, when thecontact piece 51 is disposed in the +Z direction relative to the second reference position, the first biasingmember 52 applies the biasing force in the −Z direction to thecontact piece 51. - In contrast, when the
contact portion 515 is located in the −Z direction relative to the bottom 461, the first biasingmember 52 applies the biasing force in the +Z direction to thecontact portion 515. That is, when thecontact piece 51 is disposed in the −Z direction relative to the second reference position, the first biasingmember 52 applies the biasing force in the +Z direction to thecontact piece 51. - Although not illustrated in the drawings, when the
contact portion 515 reaches the rotation limit in the +D direction, thecontact portion 515 is disposed in the +D direction with respect to thepath forming portion 47. A position of thecontact piece 51 in the +Z direction in this case is the same as the second position. Specifically, when thecontact portion 515 is moved in the +D direction along the second path RT12, and the position in the +Z direction of thecontact portion 515 reaches a position that is the same as the position of thecontact portion 515 in the case of the second position, thecontact portion 515 is moved, in association with the rotation of therotator 42 in the −D direction, in the +D direction while being separated from thepath forming portion 47. That is, a path between the position at which thecontact portion 515 is separated from thepath forming portion 47 and the rotation limit in the +D direction of thecontact portion 515 on the second path RT12 is along the circumferential direction about the rotation axis Rx. - Here, the second path RT12 is provided at a position closer to the rotation axis Rx than the first path RT11. Thus, when reaching the second path RT12 from the first path RT11, the
contact piece 51 moves in the −Y direction that is slightly on a side of the rotation axis Rx owing to the biasing force of the second biasingmember 53. In this configuration, when therotator 42 is rotated in the +D direction in a state where thecontact portion 515 is disposed on the second path RT12, the movement of thecontact piece 51 from the second path RT12 to the first path RT11 is restricted, and the movement of thecontact piece 51 along the second path RT12 is allowed. Accordingly, when therotator 42 is rotated in the +D direction, thecontact portion 515 reaches a position PS4 inFIG. 14 , for example. - When the
rotator 42 is rotated in the +D direction in a state where thecontact portion 515 is disposed on the second path RT12 and reaches theguide surface 483, thecontact piece 51 is moved by theguide surface 483 in the +Y direction away from therotator 42. - When the
rotator 42 is further rotated in the +D direction to reach the reference position, thecontact portion 515 comes into contact with the restrictingsurface 482, as indicated by a position PS5 inFIG. 14 . The position PS5 at which thecontact portion 515 is in contact with the restrictingportion 481 is the first position in the counterclockwise range described above. This restricts the movement in the −D direction of thecontact portion 515 relative to therotator 42, and restricts the rotation of therotator 42 in the +D direction. - In a state where the
contact piece 51 is disposed at the first position, the end surface in the −Y direction of thecontact portion 515 is disposed in the +Y direction relative to thepath forming portion 47. Thecontact piece 51 is thus movable beyond thepath forming portion 47 in a direction from the first position toward the second position, i.e., in the −Z direction. In this configuration, for example, when the user releases his or her hand from theknob 43 to reduce the rotating force in the +D direction with respect to therotator 42, thecontact portion 515 moves in the −Z direction owing to the biasing force of the first biasingmember 52 and returns to the bottom 461. That is, thecontact piece 51 returns to the second position. - This allows the
contact portion 515 to move relatively in the ±D directions with respect to therotator 42, thereby allowing therotator 42 to rotate in the ±D directions. - When the
rotator 42 is rotated in the +D direction in the state where thecontact piece 51 is disposed at the second position where thecontact portion 515 is located on the bottom 461, thecontact portion 515 moves relatively in the −D direction with respect to therotator 42 along theinclined portion 463, and moves relatively with respect to therotator 42 along the first path RT21 and the second path RT22. When therotator 42 is rotated in the −D direction and thecontact portion 515 moved along the second path RT22 and theguide surface 473 reaches the restrictingportion 471, the restrictingportion 471 restricts the rotation in the −D direction of therotator 42. The position of thecontact piece 51 when thecontact portion 515 comes into contact with the restrictingportion 471 is the first position in the clockwise-side range described above. - When the rotating force in the −D direction applied to the
rotator 42 is reduced in this state, thecontact portion 515 moves in the +Z direction owing to the biasing force of the first biasingmember 52 and thecontact piece 51 returns to the second position. - This allows the
contact portion 515 to move relatively in the ±D directions with respect to therotator 42, thereby allowing therotator 42 to rotate in the ±D directions. - Here, the
contact piece 51 moves in the +Y direction as thecontact piece 51 moves in the +D direction along theguide surface 473. Thus, when thecontact piece 51 is disposed at the first position that is in contact with the restrictingportion 471, thecontact piece 51 is movable beyond thepath forming portion 47 from the first position to the second position. - Similarly, the
contact piece 51 moves in the +Y direction as thecontact piece 51 moves in the −D direction along theguide surface 483. Thus, when thecontact piece 51 is disposed at the first position that is in contact with the restrictingportion 481, thecontact piece 51 is movable beyond thepath forming portion 48 from the first position to the second position. -
FIG. 15 illustrates a cross section along an XZ plane of therotary operator 2 taken along a position of thecontact portion 515 that is inserted through theguide hole 343 in the −Y direction. In other words,FIG. 15 illustrates a cross section of therotary operator 2 taken along a line XV-XV indicated inFIG. 5 . InFIG. 15 , thecontact piece 51 is disposed at the second position. - However, upon the rotation in the +D direction of the
rotator 42 in the counterclockwise-side range, thecontact piece 51 is pushed out in the +Y direction by theguide surface 473, and is simultaneously pressed against aninner surface 343A provided in the +X direction of theguide hole 343 as illustrated inFIG. 15 . Further, upon the rotation in the −D direction of therotator 42 in the clockwise-side range, thecontact piece 51 is pushed out in the +Y direction by theguide surface 483, and is simultaneously pressed against aninner surface 343B provided in the −X direction of theguide hole 343. Thecontact portion 515 is thus in a state of being caught between theguide surface 473 and the inner surface 3438, or in a state of being caught between theguide surface 483 and theinner surface 343A. In this case, it is difficult for thecontact piece 51 to move from the first position to the second position. - Whether or not the
contact piece 51 moves to the second position while being pushed out in the +Y direction by theguide surface 473 or theguide surface 483 depends on a balance between the biasing force of the first biasingmember 52 and the biasing force of the second biasingmember 53. - For example, setting the biasing force of the first biasing
member 52 to be lower than a first threshold and setting the biasing force of the second biasingmember 53 to be higher than a second threshold make it possible to configure therotary operator 2 such that no movement toward the second position is generated during the rotation of therotator 42, i.e., when a torque that makes therotator 42 rotatable is applied to theknob 43. - Further, for example, setting the biasing force of the first biasing
member 52 to be higher than the first threshold and setting the biasing force of the second biasingmember 53 to be lower than the second threshold make it possible to configure therotary operator 2 such that thecontact piece 51 reaches the second position prior to reaching the restrictingsurface 472 or the restrictingsurface 482, unless therotator 42 is rotated above a predetermined rotation rate. In this case, therotary operator 2 can be configured such that: the restrictingsurface 472 does not restrict the movement of thecontact piece 51 in the +D direction, i.e., the rotation of therotator 42 in the −D direction; and the restrictingsurface 482 does not restrict the movement of thecontact piece 51 in the −D direction, i.e., the rotation of therotator 42 in the +D direction. - Configuration of Operational-Feeling Switching Mechanism
FIGS. 16 and 17 are each an exploded perspective view of theoperator body 4 and the operational-feeling switching mechanism 6. Specifically,FIG. 16 is the exploded perspective view of theoperator body 4 and the operational-feeling switching mechanism 6 viewed from the +Z direction, andFIG. 17 is the exploded perspective view of theoperator body 4 and the operational-feeling switching mechanism 6 viewed from the −Z direction. - The operational-
feeling switching mechanism 6 switches the operational feelings of therotary operator 2 in response to the switching operation on thestate switching mechanism 7 to be described later, along with the switching of the operation modes performed by thestate switching mechanism 7. In the exemplary embodiment, the operational feelings are clicking feelings, and the operational-feeling switching mechanism 6 performs switching between a state where a clicking feeling occurs when therotator 42 is rotated and a state where no clicking feeling occurs when therotator 42 is rotated. - The operational-
feeling switching mechanism 6 is provided between thecover 38 and thecylindrical portion 45 of therotator 42 in thefirst arrangement portion 32 of thecasing 3. As illustrated inFIGS. 16 and 17 , the operational-feeling switching mechanism 6 includes theclick plate 61, themovement base 62, and a biasingmember 63. - Configuration of Click Plate
- The
click plate 61 is provided in the +Z direction with respect to thecylindrical portion 45, and is moved by themovement base 62 in the −Z direction toward thecylindrical portion 45 of therotator 42 or in the +Z direction away from thecylindrical portion 45. Theclick plate 61 corresponds to an engagement member, and is engageable with thecylindrical portion 45 when moved in the −Z direction. Theclick plate 61 includes aplate body 611, the to-be-guided portion 612, anengagement portion 613, and theprotrusion 614. - The
plate body 611 has a ring shape. Theplate body 611 has anopening 6111 having a circular shape into which a portion in the +Z direction of therotating body 44 is to be inserted. Theplate body 611 has a surface in the +Z direction provided with twoarrangement portions 6112 that are recessed in the −Z direction. - The two
arrangement portions 6112 are provided at positions sandwiching a center portion of theclick plate 61 as viewed from the +Z direction. The biasingmember 63 is provided inside each of thearrangement portions 6112. - The to-
be-guided portion 612 is a part that protrudes radially outward from an outer periphery of theplate body 611. Theplate body 611 is provided with three to-be-guided portions 612. The to-be-guided portions 612 are each disposed in the corresponding one of theguides 321 to 323 provided in thecasing 3 to restrict rotation of theclick plate 61 about the rotation axis Rx and to guide the movement in the ±Z directions. - As with the to-
be-guided portion 612, theengagement portion 613 is a part that protrudes radially outward from the outer periphery of theplate body 611. Theplate body 611 is provided with threeengagement portions 613. Each of theengagement portions 613 engages with aninclined portion 624 of themovement base 62. - As illustrated in
FIG. 17 , theprotrusion 614 is provided in each of two to-be-guided portions 612 that are provided at both ends in the +X direction of theplate body 611, out of the three to-be-guided portions 612. Each of theprotrusions 614 protrudes in a substantially truncated quadrangular pyramid shape in the −Z direction from a surface in the −Z direction of the to-be-guided portion 612. That is, theprotrusion 614 has an inclined surface facing the +Y direction and an inclined surface facing the −Y direction. In other words, theprotrusion 614 has an inclined surface facing the +D direction and an inclined surface facing the −D direction. - The
protrusion 614 fits into thefitting portion 451 when therotator 42 is rotated to generate the clicking feeling. A position of thefitting portion 451 in therotator 42 and a position of theprotrusion 614 in theclick plate 61 are defined such that the clicking feeling occurs when, for example, therotator 42 is disposed at a first reference position. - The
click plate 61 is movable in the ±Z directions. Theprotrusion 614 is thus separated from thefitting portion 451 when therotator 42 is further rotated in the state where theprotrusion 614 is fitted into thefitting portion 451. - Configuration of Movement Base
- The
movement base 62 is provided to be rotatable about the rotation axis Rx of therotator 42. Themovement base 62 engages with theslide member 72 of thestate switching mechanism 7 to be described later, and moves theclick plate 61 in the ±Z directions in association with movement in the ±Y directions of theslide member 72. That is, themovement base 62 is a movement member that moves theclick plate 61 closer to or away from thefitting portion 451 of therotator 42 in association with the sliding of theslide member 72. As illustrated inFIGS. 16 and 17 , themovement base 62 includes abase body 621, two extendingportions 622, a connectingportion 623, and theinclined portion 624. - The
base body 621 has a ring shape. Thebase body 621 has anopening 6211 having a circular shape into which a portion in the +Z direction of therotating body 44 is to be inserted. - The two extending
portions 622 extend radially outward from a periphery of thebase body 621 as viewed from the +Z direction and in opposite directions to each other. Specifically, one of the two extendingportions 622 extends in the +Y direction and the other extends in the −Y direction. - The connecting
portion 623 connects ends in the −X direction of the respective extendingportions 622 to each other. The connectingportion 623 includes anengagement portion 6231 that is provided on an end in the −X direction to be engaged with theslide member 72. That is, the operational-feeling switching mechanism 6 includes theengagement portion 6231 that engages with theslide member 72. Theengagement portion 6231 has a cylindrical shape protruding in the −Z direction from the connectingportion 623. - As illustrated in
FIG. 16 , theinclined portions 624 are provided in ends in the +X direction and ends in the −X direction of the respective extendingportions 622. That is, themovement base 62 includes fourinclined portions 624. Each of theinclined portions 624 is inclined to the circumferential direction about the rotation axis of themovement base 62. More specifically, theinclined portion 624 is inclined to face the +Z direction and the counterclockwise direction about the rotation axis Rx as viewed from the +Z direction. Theinclined portion 624 pushes up in the +Z direction theengagement portion 613 and the to-be-guided portion 612 in the −X direction in association with the counterclockwise rotation as viewed from the +Z direction of themovement base 62, and thus separates theclick plate 61 from thecylindrical portion 45. In this configuration, even when therotator 42 is rotated, theprotrusion 614 is not fitted to thefitting portion 451, and no clicking feeling occurs. - Configuration of Biasing Member
- The biasing
member 63 biases theclick plate 61 in the −Z direction. As illustrated inFIG. 16 , the biasingmember 63 is provided in thecorresponding arrangement portion 6112 and is disposed between thecover 38 and theclick plate 61. That is, the operational-feeling switching mechanism 6 includes two biasingmembers 63. An end in the +Z direction of each of the biasingmembers 63 is in contact with a surface in the −Z direction of thecover 38 and an end in the −Z direction of each of the biasingmembers 63 is in contact with theclick plate 61. - Action of Operational-Feeling Switching Mechanism
- When the
click plate 61 is not moved in the +Z direction by themovement base 62, theclick plate 61 is biased by the biasingmember 63 in the direction toward thecylindrical portion 45 of therotating body 44, and is disposed at a position where theprotrusion 614 is fittable in thefitting portion 451 in the +Z direction. That is, theclick plate 61 is disposed at a position at which the clicking feeling can occur. - In contrast, when the
movement base 62 is rotated counterclockwise as viewed from the +Z direction and theclick plate 61 is moved in the +Z direction against the biasing force of the biasingmember 63, theprotrusion 614 is separated in the +Z direction from thefitting portion 451. This causes theprotrusion 614 to be disposed at a position at which theprotrusion 614 cannot fit in thefitting portion 451 in the +Z direction. That is, theclick plate 61 is disposed at a position at which the clicking feeling cannot occur. - Such rotation of the
movement base 62 is performed by the sliding of theslide member 72 with which themovement base 62 engages. - Configuration of State Switching Mechanism
-
FIG. 18 is a perspective view of a portion of thestate switching mechanism 7 and onerotary operator 2. More specifically,FIG. 18 is the perspective view illustrating a portion of thestate switching mechanism 7 and therotary operator 2 that configures theeffect adjuster 157A.FIG. 19 is an exploded perspective view of a portion of thestate switching mechanism 7. - The
state switching mechanism 7 switches the operation modes and the operational feelings of therotary operator 2 as described above. As illustrated inFIGS. 2, 18, and 19 , thestate switching mechanism 7 includes aslide switch 71 and theslide member 72. - Configuration of Slide Switch
- As illustrated in
FIGS. 18 and 19 , theslide switch 71 includes theslide operator 711, and aholder 712 that holds theslide operator 711. Theslide switch 71 switches the operation modes of therotary operator 2 in accordance with the position of theslide operator 711. - The
slide operator 711 is exposed on the microphone adjuster 12 (see,FIG. 1 ) on thetop surface 11A of thecasing 11. Theslide operator 711 is provided to be slidable in the +Y direction in theholder 712. Theslide operator 711 is allocatable at three positions along the +Y direction. That is, theslide operator 711 is allocatable at one switching position out of a first switching position, a second switching position that is a position in the +Y direction with respect to the first switching position, and a third switching position that is a position in the +Y direction with respect to the second switching position. - The
holder 712 is fixed in thecasing 11. Theholder 712 outputs an operation signal corresponding to the position of theslide operator 711 to the controller (not illustrated) that controls theacoustic device 1, and switches the operation modes of therotary operator 2. - Setting of the operation modes in accordance with the disposition position of the
slide operator 711 will be described in detail later. - Configuration of Slide Member
- The
slide member 72 is provided in thecasing 11 to be slidable in response to a slide operation on theslide operator 711. That is, theslide member 72 slides with theslide operator 711 in the same direction as a direction in which theslide operator 711 slides. Theslide member 72 includes afirst slide member 73, anelastic member 74, a biasingmember 75, and asecond slide member 76. - The
first slide member 73 engages with theslide operator 711 and slides in the ±Y directions with theslide operator 711. Thefirst slide member 73 has oneopening 731 as illustrated inFIGS. 2, 18, and 19 , and includes a holdingportion 732 as illustrated inFIG. 2 . - The
slide operator 711 is inserted from the −Z direction into theopening 731. An inner diameter of theopening 731 is the substantially same as an outer diameter of theslide operator 711. Theslide operator 711 is thus exposed from theopening 731 in the +Z direction. Sliding in the ±Y directions theslide operator 711 exposed on thetop surface 11A of thecasing 11 causes thefirst slide member 73 to slide in the same direction as the slide direction of theslide operator 711. - The holding
portion 732 holds theelastic member 74, the biasingmember 75, and thesecond slide member 76. The number of each of the holdingportions 732, theelastic members 74, the biasingmembers 75, and thesecond slide members 76 is determined in accordance with the number of therotary operators 2. As illustrated inFIG. 2 , the holdingportion 732 includes a holdingportion 732A corresponding to therotary operator 2 that configures theeffect adjuster 157A, a holdingportion 732B corresponding to therotary operator 2 that configures theeffect adjuster 157B, a holdingportion 732C corresponding to therotary operator 2 that configures theeffect adjuster 157C, and a holdingportion 732D corresponding to therotary operator 2 that configures theeffect adjuster 157D. - As illustrated in
FIGS. 18 and 19 , the holdingportion 732A includes anarrangement portion 733, twoclamp pieces 734, twoengagement pieces 735, and anopening 736. - The
arrangement portion 733 is a wall along an XY plane. On thearrangement portion 733, theelastic member 74 is fixed, and in addition, the biasingmember 75 and thesecond slide member 76 are disposed. - The two
clamp pieces 734 are provided at respective positions opposed to thearrangement portion 733 in the +Z direction. The twoclamp pieces 734 clamp, between themselves and thearrangement portion 733, the biasingmember 75 and thesecond slide member 76 disposed on thearrangement portion 733. - The two
engagement pieces 735 protrude in the +Z direction from an end in the +X direction of thearrangement portion 733. The twoengagement pieces 735 restrict the biasingmember 75 and thesecond slide member 76 disposed on thearrangement portion 733 from sliding in the +X direction. Theengagement portion 6231 of themovement base 62 is disposed between the twoengagement pieces 735. Thus, when theslide member 72 is slid in the −Y direction, theslide member 72 causes themovement base 62 to rotate counterclockwise as viewed from the +Z direction, and when theslide member 72 is slid in the +Y direction, theslide member 72 causes themovement base 62 to rotate clockwise as viewed from the +Z direction. - The
opening 736 is an opening having a rectangular shape that is long in the +Y direction. Theengagement portion 552 of the switchingmember 55 is inserted into theopening 736. - The holding
portions portion 732A, and thus the descriptions thereof are omitted. - Configurations of Elastic Member and Biasing Member
- As illustrated in
FIG. 19 , theelastic member 74 is a member that is provided on a surface in the +Z direction of thearrangement portion 733 and fills a gap between thearrangement portion 733 and thesecond slide member 76 provided on thearrangement portion 733. Theelastic member 74 inhibits unintentional sliding of thesecond slide member 76 along the XY plane. - The biasing
member 75 is a member that biases thesecond slide member 76 toward thefirst slide member 73. In the exemplary embodiment, a leaf spring is employed as the biasingmember 75. The biasingmember 75 is disposed between theclamp piece 734 and thearrangement portion 733 to bias thesecond slide member 76 toward thearrangement portion 733. Anopening 751 along the +Y direction is provided in the middle of the biasingmember 75 as viewed from the +Z direction, and aninsertion portion 761 of thesecond slide member 76 is inserted into theopening 751. - Configuration of Second Slide Member
- The
second slide member 76 is provided on thearrangement portion 733 of thefirst slide member 73 to be slidable in the ±Y directions that are the slide directions of thefirst slide member 73. Thesecond slide member 76 causes the switchingmember 55 of the correspondingrotary operator 2 to rotate. Thesecond slide member 76 is provided to absorb tolerances of components including, without limitation, therestriction switching mechanism 5 and thefirst slide member 73. Thesecond slide member 76 includes theinsertion portion 761, a restrictingpiece 762, arecess 763, and a throughopening 764. - The
insertion portion 761 protrudes in the +Z direction from approximately the middle of thesecond slide member 76 as viewed from the +Z direction. Theinsertion portion 761 is inserted into theopening 751 of the biasingmember 75. - Two restricting
pieces 762 are provided on a surface in the +Z direction of thesecond slide member 76, and the two restrictingpieces 762 are separated from each other in the +Y direction. The biasingmember 75 is disposed between the two restrictingpieces 762, and in addition, the twoclamp pieces 734 are sandwiched between the two restrictingpieces 762 in the +Y direction. As a result, a slidable range in the +Y direction of thesecond slide member 76 is defined. - The
recess 763 is provided on an end surface in the +X direction of thesecond slide member 76. Therecess 763, which is recessed in the −X direction, is a part for avoiding theengagement portion 6231 of themovement base 62 that engages with the twoengagement pieces 735. - The through
opening 764 is an opening provided in a part in the +Y direction of thesecond slide member 76. The throughopening 764 passes through thesecond slide member 76 along the +Z direction. Theengagement portion 552 of the switchingmember 55 is inserted into the throughopening 764. When theslide member 72 slides in the −Y direction, an inner surface in the −Y direction out of inner surfaces of the throughopening 764 presses theengagement portion 552 in the +Y direction to cause the switchingmember 55 to rotate clockwise as viewed from the +Z direction. - Action of State Switching Mechanism
- As described above, the
slide operator 711 is slid in the ±Y directions and is thereby disposed at one of the first switching position, the second switching position, or the third switching position. Further, theslide member 72 is engaged with theslide operator 711, and thus slides in the ±Y directions together with theslide operator 711. -
FIG. 20 is a plan view of thestate switching mechanism 7 in a state where theslide operator 711 is disposed at the first switching position. InFIG. 20 , a chain line L1 indicates a position of an end in the −Y direction of theslide operator 711 disposed at the first switching position. A chain line L2 indicates a position of the end in the −Y direction of theslide operator 711 disposed at the second switching position. A chain line L3 indicates a position of the end in the −Y direction of theslide operator 711 disposed at the third switching position. - As illustrated in
FIG. 20 , when an operation of disposing theslide operator 711 at the first switching position is performed, theholder 712 outputs, to the controller, an operation signal for switching the operation mode of therotary operator 2, and thus the operation mode of theacoustic device 1, to a first mode. The controller to which the signal for switching the operation mode to the first mode is inputted switches the operation mode of therotary operator 2 to the first mode. - When the
slide operator 711 is disposed at the first switching position, theslide member 72 is disposed farthest in the −Y direction in a movable range of theslide member 72. - In this case, the
movement base 62 engaged with theslide member 72 causes theclick plate 61 of the operational-feeling switching mechanism 6 to be disposed at a position at which theprotrusion 614 does not fit into thefitting portion 451 even when therotator 42 is rotated. In other words, themovement base 62 disposes theclick plate 61 at a position at which no clicking feeling occurs even when therotator 42 is rotated. - Further, the holding
member 54 and thecontact piece 51 are biased by the third biasingmember 56, and are disposed at respective positions that are separated in the +Y direction from therotator 42 by the switchingmember 55 engaged with theslide member 72. In this state, thecontact portion 515 is separated from therotator 42, and thus the rotation of therotator 42 that passes the reference position is not restricted by thecontact piece 51. - In the exemplary embodiment, the first mode is an operation mode for setting an effect amount of one effect by the whole rotatable range of the
rotator 42 including the reference position. That is, the first mode is a mode in which the effect amount of one effect is set based on the rotation angle of therotator 42 with the rotation limit in the −D direction of therotator 42 being set as a minimum value, the rotation limit in the +D direction of therotator 42 being set as a maximum value. In the first mode, no clicking feeling occurs during the rotation operation of therotator 42. -
FIG. 21 is a plan view of thestate switching mechanism 7 in a state where theslide operator 711 is disposed at the second switching position. The chain lines L1 to L3 inFIG. 21 are the same as the chain lines L1 to L3 illustrated inFIG. 20 . - As illustrated in
FIG. 21 , when an operation of disposing theslide operator 711 at the second switching position is performed, theholder 712 outputs, to the controller, an operation signal for switching the operation mode of therotary operator 2, and thus the operation mode of theacoustic device 1, to a second mode. The controller to which the signal for switching the operation mode to the second mode is inputted switches the operation mode of therotary operator 2 to the second mode. - When the
slide operator 711 is disposed at the second switching position, theslide member 72 is disposed substantially in the middle in the movable range of theslide member 72. - In this case, the
click plate 61 of the operational-feeling switching mechanism 6 is disposed at a position at which theprotrusion 614 is fittable in thefitting portion 451 by themovement base 62. That is, theclick plate 61 is disposed by themovement base 62 at a position at which the clicking feeling occurs when therotator 42 is rotated. - In contrast, as with the case where the
slide operator 711 is disposed at the first switching position, the holdingmember 54 and thecontact piece 51 are disposed at respective positions that are separated in the +Y direction from therotator 42 by the switchingmember 55. Accordingly, thecontact portion 515 is separated from therotator 42, and thus the rotation of therotator 42 that passes the reference position is not restricted by thecontact piece 51. - In the exemplary embodiment, the second mode is an operation mode in which: when the
rotator 42 is rotated in the +D direction from the reference position, an effect amount of a first effect is set in accordance with the rotation angle of therotator 42 from the reference position toward the +D direction; and when therotator 42 is rotated in the −D direction from the reference position, an effect amount of a second effect is set in accordance with the rotation angle of therotator 42 from the reference position toward the −D direction. In the second mode, the clicking feeling occurs during the rotation operation of therotator 42. -
FIG. 22 is a plan view of thestate switching mechanism 7 in a state where theslide operator 711 is disposed at the third switching position. The chain lines L1 to L3 inFIG. 22 are the same as the chain lines L1 to L3 illustrated inFIG. 20 . - As illustrated in
FIG. 22 , when an operation of disposing theslide operator 711 at the third switching position is performed, theholder 712 outputs, to the controller, an operation signal for switching the operation mode of therotary operator 2, and thus the operation mode of theacoustic device 1, to the third mode. - When the
slide operator 711 is disposed at the third switching position, theslide member 72 is disposed farthest in the +Y direction in the movable range of theslide member 72. - In this case, as with the case where the
slide operator 711 is disposed at the second switching position, theclick plate 61 of the operational-feeling switching mechanism 6 is disposed at a position at which theprotrusion 614 is fittable in thefitting portion 451 by themovement base 62. That is, theclick plate 61 is disposed by themovement base 62 at a position at which the clicking feeling occurs when therotator 42 is rotated. - Further, when the
slide member 72 is disposed at the third switching position, the biasing in the +Y direction on the holdingmember 54 by the switchingmember 55, which is rotated clockwise as viewed from the +Z direction by theslide member 72, is released. Accordingly, the holdingmember 54 is biased in the −Y direction by the second biasingmember 53, and thecontact piece 51 is thus biased toward the rotation axis Rx. This causes thecontact portion 515 to come into contact with therotator 42. Thecontact portion 515 moves along the movement paths RT1 and RT2 in association with the rotation of therotator 42, and the rotation of therotator 42 that passes the reference position is restricted. - As described above, in the third mode, the clicking feeling occurs during the rotation operation of the
rotator 42. In contrast, unlike the case in the second mode, the rotation of therotator 42 that passes the reference position is restricted in the third mode. - In the exemplary embodiment, as with the second mode, the third mode is an operation mode in which the effect amount of the first effect is set in accordance with the rotation angle of the
rotator 42 from the reference position toward the +D direction, and the effect amount of the second effect is set in accordance with the rotation angle of therotator 42 from the reference position toward the −D direction. Accordingly, upon adjustment on the effect amount of one of the first effect and the second effect, the effect amount of the other effect is prevented from being erroneously adjusted. - As described above, by slidingly moving in the ±Y directions the
slide operator 711 that is an operation knob exposed on thetop surface 11A of thecasing 11, it is possible to not only switch the operation modes of each of therotary operators 2 that configure theeffect adjusters 157A to 157D, but also to simultaneously switch the operational feelings of each of therotary operators 2 and the restricted states of each of therotary operators 2. - The
acoustic device 1 according to the exemplary embodiment described above can achieve the following effects. - The
acoustic device 1 includes therotary operator 2. - The
rotary operator 2 includes therotator 42 and thecontact piece 51. The movement paths RT1 and RT2 inclined to the circumferential direction about the rotation axis Rx are provided for the outercircumferential surface 45A. Therotator 42 is rotated about the rotation axis Rx. Thecontact piece 51 comes into contact with therotator 42, and moves along the movement paths RT1 and RT2 in the direction along the rotation axis Rx in association with the rotation of therotator 42. - In the counterclockwise-side range, the rotation of the
rotator 42 in the +D direction (a first rotation direction) about the rotation axis Rx is restricted by thecontact piece 51 being located at the first position in the counterclockwise range when therotator 42 is rotated in the +D direction and reaches the reference position. The +D direction is the clockwise direction as viewed from the +Z direction. - When the rotating force in the +D direction applied to the
rotator 42 is reduced in the state where the rotation of therotator 42 in the +D direction from the reference position is restricted, thecontact piece 51 returns to the second position from the first position, thereby allowing the rotation of therotator 42 in the +D direction from the reference position. - Further, in the clockwise-side range, the rotation of the
rotator 42 in the −D direction (the first rotation direction) about the rotation axis Rx is restricted by thecontact piece 51 being located at the first position in the clockwise-side range when therotator 42 is rotated in the −D direction and reaches the reference position. The −D direction is the counterclockwise direction as viewed from the +Z direction. - When the rotating force in the −D direction applied to the
rotator 42 is reduced in the state where the rotation of therotator 42 in the −D direction from the reference position is restricted, thecontact piece 51 returns to the second position from the first position, thereby allowing the rotation of therotator 42 in the −D direction from reference position. - With such a configuration, it is possible to restrict the
rotator 42 rotated in the +D direction from being erroneously rotated in the +D direction beyond the reference position. This makes it possible to easily rotate therotator 42 in the ±D directions in the rotation range (the counterclockwise-side range) from the reference position to the rotation limit in the −D direction. When therotator 42 rotated in the +D direction reaches the reference position, the rotating force in the +D direction applied to therotator 42 is reduced, whereby thecontact piece 51 returns to the second position from the first position and it is possible to rotate therotator 42 in the +D direction from the reference position. This makes it possible not only to restrict the rotation of therotator 42 in the +D direction from the reference position, but also to allow the rotation of therotator 42 in the +D direction from the reference position. - Similarly, it is possible to restrict the
rotator 42 rotated in the −D direction from being erroneously rotated in the −D direction beyond the reference position. This makes it possible to easily rotate therotator 42 in the ±D directions in the rotation range (the clockwise-side range) from the reference position to the rotation limit in the +D direction. When therotator 42 rotated in the −D direction reaches the reference position, the rotating force in the −D direction applied to therotator 42 is reduced, whereby thecontact piece 51 returns to the second position from the first position and it is possible to rotate therotator 42 in the −D direction from the reference position. This makes it possible not only to restrict the rotation of therotator 42 in the −D direction from the reference position, but also to allow the rotation of therotator 42 in the −D direction from the reference position. - Operability of the
rotary operator 2 is thus improved. - The
rotary operator 2 includes the first biasingmember 52 that biases thecontact piece 51 in a direction from the first position toward the second position. - With such a configuration, it is possible to easily cause the
contact piece 51 to return to the second position from the first position in the counterclockwise-side range, when the rotating force in the +D direction applied to therotator 42 is reduced in the state where the rotation of therotator 42 in the +D direction (the first rotation direction) from the reference position is restricted in the counterclockwise-side range. Similarly, it is possible to easily cause thecontact piece 51 to return to the second position from the first position in the clockwise-side range, when the rotating force in the −D direction applied to therotator 42 is reduced in the state where the rotation of therotator 42 in the −D direction (the first rotation direction) from the reference position is restricted in the clockwise-side range. It is therefore possible to easily perform the rotation of therotator 42 in the ±D directions from the reference position, and to improve operability of therotary operator 2. - In the
rotary operator 2, therotator 42 includes the restrictingportions - The restricting
portion 471 comes into contact with thecontact portion 515 of thecontact piece 51 when therotator 42 is rotated in the −D direction (the first rotation direction) and reaches the reference position in the clockwise-side range, and restricts the relative movement in the +D direction (the direction opposite to the first rotation direction) of thecontact piece 51 with respect to therotator 42. That is, the restrictingportion 471 restricts therotator 42 from rotating in the −D direction from the reference position in the clockwise-side range. - The restricting
portion 481 comes into contact with thecontact portion 515 of thecontact piece 51 when therotator 42 is rotated in the +D direction (the first rotation direction) and reaches the reference position in the counterclockwise-side range, and restricts the relative movement in the −D direction (the direction opposite to the first rotation direction) of thecontact piece 51 with respect to therotator 42. That is, the restrictingportion 481 restricts therotator 42 from rotating in the +D direction from the reference position in the counterclockwise-side range. - With such a configuration, it is possible to restrict the
rotator 42 from rotating in the −D direction from the reference position in the clockwise-side range by thecontact piece 51 coming into contact with the restrictingportion 471. Further, it is possible to restrict therotator 42 from rotating in the +D direction from the reference position in the counterclockwise-side range by thecontact piece 51 coming into contact with the restrictingportion 481. - Operability of the
rotary operator 2 is thus improved. - In the
rotary operator 2, the movement path RT1 includes the first path RT11 and the second path RT12. The first path RT11 is a path along which thecontact piece 51 moves relatively in the +D direction (the direction opposite to the first rotation direction) with respect to therotator 42 from the second position, when therotator 42 is rotated in the −D direction (the first rotation direction) from the reference position. The second path RT12 is a path by which thecontact piece 51 is led to the restrictingportion 481 when therotator 42, which has been rotated in the −D direction from the reference position in the counterclockwise-side range, is rotated in the +D direction. That is, the second path RT12 is a path by which thecontact piece 51 is led to the first position in the counterclockwise-side range when therotator 42, which has been rotated in the −D direction from the reference position in the counterclockwise-side range, is rotated in the +D direction. - With such a configuration, when the
rotator 42 rotated in the +D direction reaches the reference position in the state where thecontact piece 51 reaches the second path RT12, it is possible to lead thecontact piece 51 to the first position. Accordingly, it is possible to restrict therotator 42 rotated in the +D direction from being rotated in the +D direction beyond the reference position. - This applies similarly to the movement path RT2 including the first path RT21 and the second path RT22, and thus it is possible to restrict the
rotator 42 rotated in the −D direction from being rotated in the −D direction beyond the reference position. - In the
rotary operator 2, a length of the first path RT11 in the −D direction (the first rotation direction) is shorter than a length of the second path RT12 in the −D direction. A length of the first path RT21 in the +D direction (the first rotation direction) is shorter than a length of the second path RT22 in the +D direction. - With such a configuration, it is possible to cause the
contact portion 515 disposed at the second position to reach the second path RT12 with a small rotation amount of therotator 42 from the reference position. The second path RT12 is a path from a movement limit in the +D direction of thecontact portion 515 to the first position in the counterclockwise-side range when therotator 42 is located in the counterclockwise-side range. In this configuration, when therotator 42 is rotated in the +D direction and reaches the reference position in the counterclockwise range, it is possible to cause thecontact portion 515 to reach the first position in the counterclockwise-side range. This makes it possible to restrict the rotation in the +D direction of therotator 42 that passes the reference position. - Similarly, it is possible to cause the
contact portion 515 disposed at the second position to reach the second path RT22 with a small rotation amount of therotator 42 from the reference position, which makes it possible to restrict the rotation in the −D direction of therotator 42 that passes the reference position. - The
rotary operator 2 includes the second biasingmember 53 that biases thecontact piece 51 toward the rotation axis Rx. The second path RT12 is provided at a position closer to the rotation axis Rx than the first path RT11, and the second path RT22 is provided at a position closer to the rotation axis Rx than the first path RT21. - With such a configuration, it is possible to prevent the
contact piece 51 that has moved from the first path RT11 to the second path RT12 from returning to the first path RT11. Further, it is possible to prevent thecontact piece 51 that has moved from the first path RT21 to the second path RT22 from returning to the first path RT21. Accordingly, it is possible to restrict the rotation of therotator 42 in the ±D directions that passes the reference position. - The reference position that is a predetermined position is a position where the length from the reference position to the rotation limit in the −D direction of the
rotator 42 is equal to the length from the reference position to the rotation limit in the +D direction of therotator 42. - With such a configuration, the reference position is a middle position in the entire rotatable range of the
rotator 42. This makes it possible to allow the rotatable range in the +D direction from the reference position and the rotatable range in the −D direction from the reference position to be equal to each other. Usability of therotary operator 2 is thus improved. - In the
acoustic device 1, when the operation mode of theacoustic device 1 and therotary operator 2 is the third mode in which the rotation of therotator 42 that passes the reference position is restricted, therotary operator 2 configures theeffect adjuster 157 that adjusts the effect amount of the first effect in accordance with the rotation angle of therotator 42 from the reference position toward the +D direction (the first rotation direction), and adjusts the effect amount of the second effect in accordance with the rotation angle of therotator 42 from the reference position toward the −D direction. - With such a configuration, for example, the rotation of the
rotator 42 in the +D direction that passes the reference position is restricted, preventing the effect amount of the first effect from being erroneously adjusted when the effect amount of the second effect is being adjusted. Further, for example, the rotation of therotator 42 in the −D direction that passes the reference position is restricted, preventing the effect amount of the second effect from being erroneously adjusted when the effect amount of the first effect is being adjusted. Usability of theacoustic device 1 is thus improved. - Next, a second exemplary embodiment of the disclosure will be described.
- An acoustic device according to the exemplary embodiment has a configuration similar to that of the
acoustic device 1 according to the first exemplary embodiment, but is different from theacoustic device 1 according to the first exemplary embodiment in that a path forming portion included in a rotator of a rotary operator is different in configuration as compared with theacoustic device 1 according to the first exemplary embodiment. In the following description, the same or substantially the same portions as those already described are denoted by the same reference numerals, and the description thereof is omitted. - Configuration of Rotary Operator
-
FIG. 23 schematically illustrates acylindrical portion 49 included in anoperator body 4A of arotary operator 2A included in the acoustic device according to the exemplary embodiment.FIG. 23 illustrates thecontact portion 515 of thecontact piece 51 that moves relatively to theoperator body 4A along thecylindrical portion 49, and in addition, positions PT1 to PT8 at which thecontact portion 515 may be disposed. - The acoustic device according to the exemplary embodiment has a configuration and a function similar to those of the
acoustic device 1 according to the first exemplary embodiment except that the acoustic device according to the exemplary embodiment includes therotary operator 2A illustrated inFIG. 23 instead of therotary operator 2. - As with the
rotary operator 2, therotary operator 2A is an operator to be rotated about the rotation axis Rx by a user. Therotary operator 2A configures, for example, each of theeffect adjusters 157A to 157D. Therotary operator 2A has a configuration and a function similar to those of therotary operator 2 except that therotary operator 2A includes theoperator body 4A instead of theoperator body 4. - Configuration of Operator Body
- As with the
operator body 4 according to the first exemplary embodiment, theoperator body 4A is a rotary volume that is to be rotated by the user and outputs a rotation angle with respect to a reference position. Theoperator body 4A includes the above-describedbase 41 and arotator 42A. - The
rotator 42A includes the above-describedknob 43 and a rotating body 44A. - The rotating body 44A has a configuration similar to that of the
rotating body 44 except that the rotating body 44A has thecylindrical portion 49 instead of thecylindrical portion 45. - The
cylindrical portion 49 has a cylindrical shape about the rotation axis Rx of therotator 42A in the rotating body 44A. Thecylindrical portion 49 includes, on an outercircumferential surface 49A,path forming portions portions cylindrical portion 49 includes thepath forming portions portions circumferential surface 49A. - As with the
path forming portions path forming portions contact portion 515 of thecontact piece 51 moves relatively with respect to therotator 42A when therotator 42A is rotated about rotation axis Rx. - As with the
path forming portion 47, thepath forming portion 491 forms the movement path RT3 of thecontact portion 515 when therotator 42A is rotated in the counterclockwise-side range. The movement path RT3 is inclined to the circumferential direction about the rotation axis Rx. That is, the movement path RT3 inclined to the circumferential direction about the rotation axis Rx is provided for the outercircumferential surface 49A of therotator 42A. - As with the restricting
portion 481, when therotator 42A disposed in the counterclockwise-side range is rotated in the +D direction, i.e., the clockwise direction, and reaches the reference position, thecontact portion 515 moving in the −D direction comes into contact with the restrictingportion 492, and the restrictingportion 492 restricts the movement in the −D direction of thecontact portion 515 and thus the rotation in the +D direction of therotator 42A. - As with the
path forming portion 48, thepath forming portion 493 forms the movement path RT4 of thecontact portion 515 when therotator 42A disposed in the clockwise-side range is rotated. The movement path RT4 is inclined to the circumferential direction about the rotation axis Rx. That is, the movement path RT4 inclined to the circumferential direction about the rotation axis Rx is provided for the outercircumferential surface 49A of therotator 42A. - As with the restricting
portion 471, when therotator 42A disposed in the clockwise-side range is rotated in the −D direction and reaches the reference position, thecontact portion 515 moving in the +D direction comes into contact with the restrictingportion 494, and the restrictingportion 494 restricts the movement in the +D direction of thecontact portion 515 and thus the rotation in the −D direction of therotator 42A. - As with the
path forming portion 48, thepath forming portion 493 forms the movement path RT4 of thecontact portion 515 when therotator 42A is rotated in the clockwise-side range. Thepath forming portion 491 and thepath forming portion 493 are provided on the outercircumferential surface 49A to be point-symmetric about the position PT1. Similarly, the restrictingportion 492 and the restrictingportion 494 are provided on the outercircumferential surface 49A to be point-symmetric about the position PT1. - Movement Path of Contact Portion
- The
path forming portion 491 is inclined to the +D direction and the +Z direction to be located in the +Z direction toward the +D direction. A surface in the +Z direction of thepath forming portion 491 forms a first path RT31, of the movement path RT3, along which thecontact portion 515 disposed at the position PT1 in the counterclockwise-side range moves in the +D direction to reach a second path RT32. A surface in the −Z direction of thepath forming portion 491 forms a portion of the second path RT32, of the movement path RT3, along which thecontact portion 515 having reached the movement limit in the +D direction in the counterclockwise-side range moves to reach the restrictingportion 492. A length in the +D direction of the first path RT31 is approximately the same as a length in the +D direction of the second path RT32. A surface in the +Z direction forming the first path RT31 in thepath forming portion 491 and a surface in the −Z direction forming the portion of the second path RT32 in thepath forming portion 491 are each inclined to the circumferential direction about the rotation axis Rx. - When the
rotator 42A located at the reference position is rotated in the −D direction, thecontact portion 515 moves along the first path RT31 and reaches, for example, the position PT2. In a state where thecontact portion 515 is located on the first path RT31, when therotator 42A is rotated in the +D direction, thecontact portion 515 moves relatively in the −D direction along the first path RT31. In this case, thecontact portion 515 does not come into contact with the restrictingportion 492, and thus the rotation of therotator 42A that passes the reference position is not restricted. - When the
rotator 42A is further rotated in the −D direction and thecontact portion 515 reaches a movement limit in the −D direction in the counterclockwise-side range, thecontact portion 515 and thepath forming portion 491 are separated from each other, and thecontact portion 515 reaches the second path RT32 that connects the movement limit in the +D direction and the position PT5 (the first position in the counterclockwise-side range). At this time, a position in the +Z direction of thecontact portion 515 matches a position in the +Z direction of thecontact portion 515 when thecontact piece 51 is disposed at the position PT1 owing to the biasing force of the first biasingmember 52. Accordingly, when therotator 42A is rotated to the rotation limit in the −D direction in the state where thecontact portion 515 is separated from thepath forming portion 491, thecontact portion 515 is moved to the movement limit in the +D direction along the second path RT32 with the position in the +Z direction unchanged. - Here, an end in the +D direction of the
path forming portion 491 is located in the +Z direction relative to an end in the +Z direction of thecontact portion 515 when thecontact piece 51 is disposed at the position PT1. Thus, when therotator 42A is rotated in the +D direction from the rotation limit in the −D direction, thecontact portion 515 comes into contact with a surface in the −Z direction of thepath forming portion 491 as indicated by the position PT3. When therotator 42A is further rotated in the +D direction, thecontact portion 515 reaches the position PT4. - In a state where the
contact portion 515 is disposed on the second path RT32, when therotator 42A is rotated in the +D direction and reaches the reference position, thecontact portion 515 reaches the position PT5 that is in contact with the restrictingportion 492 provided on an extension of the second path RT32. A position of thecontact piece 51 when thecontact portion 515 is disposed at the position PT5 corresponds to the first position in the counterclockwise-side range. Movement in the −D direction of thecontact portion 515 having reached the position PT5 is restricted by the restrictingportion 492, and thus the rotation in the +D direction of therotator 42A is restricted. That is, the rotation of therotator 42A in the +D direction from the reference position is restricted by thecontact piece 51 being at the first position in the counterclockwise-side range. - When rotating force in the +D direction applied to the
rotator 42A is reduced by, for example, the user releasing his or her finger from theknob 43, in the state where thecontact piece 51 is located at the first position, thecontact portion 515 returns to the position PT1 owing to the biasing force in the +Z direction of the first biasingmember 52. The position of thecontact piece 51 when thecontact portion 515 is disposed at the position PT1 corresponds to the second position. This allows the relative movement in the −D direction of thecontact portion 515, and thus the rotation in the +D direction of therotator 42A that passes the reference position. - The
path forming portion 493 is inclined to the −D direction and the −Z direction to be located in the −Z direction toward the −D direction. A surface in the −Z direction of thepath forming portion 493 forms a first path RT41, of the movement path RT4, along which thecontact portion 515 disposed at the position PT1 in the clockwise-side range moves in the −D direction to reach a second path RT42. A surface in the +Z direction of thepath forming portion 491 forms a portion of the second path RT42, of the movement path RT4, along which thecontact portion 515 having reached the movement limit in the −D direction in the clockwise-side range moves to reach the restrictingportion 494. A length in the +D direction of the first path RT41 is approximately the same as a length in the −D direction of the second path RT42. A surface in the −Z direction forming the first path RT41 in thepath forming portion 493 and a surface in the +Z direction forming the portion of the second path RT42 in thepath forming portion 493 are each inclined to the circumferential direction about the rotation axis Rx. - When the
rotator 42A located at the reference position is rotated in the +D direction, thecontact portion 515 moves along the first path RT41 from the position PT1, and reaches, for example, the position PT6. In a state where thecontact portion 515 is located on the first path RT41, when therotator 42A is rotated in the −D direction, thecontact portion 515 moves relatively in the +D direction along the first path RT41. In this case, thecontact portion 515 does not come into contact with the restrictingportion 494, and thus the rotation of therotator 42A that passes the reference position is not restricted. - When the
rotator 42A is further rotated in the +D direction and thecontact portion 515 reaches a movement limit in the +D direction in the clockwise-side range, thecontact portion 515 and thepath forming portion 493 are separated from each other, and thecontact portion 515 reaches the second path RT42 that connects the movement limit in the −D direction and a position PT9 (the first position in the clockwise-side range). At this time, a position in the +Z direction of thecontact portion 515 matches a position in the +Z direction of thecontact portion 515 when thecontact piece 51 is disposed at the position PT1 owing to the biasing force of the first biasingmember 52. Accordingly, when therotator 42A is rotated to the rotation limit in the +D direction in the state where thecontact portion 515 is separated from thepath forming portion 493, thecontact portion 515 is moved to the movement limit in the −D direction along the second path RT42 with the position in the +Z direction unchanged. - Here, an end in the −D direction of the
path forming portion 493 is located in the −Z direction relative to an end in the −Z direction of thecontact portion 515 when thecontact piece 51 is disposed at the position PT1. Thus, when thecontact portion 515 is moved in the +D direction by therotator 42A being rotated in the −D direction, thecontact portion 515 comes into contact with a surface on the +Z direction of thepath forming portion 493 as indicated by the position PT7. When therotator 42A is further rotated in the −D direction, thecontact portion 515 reaches the position PT8. - In a state where the
contact portion 515 is disposed on the second path RT42, when therotator 42A is rotated in the −D direction and reaches the reference position, thecontact portion 515 reaches the position PT9 that is in contact with the restrictingportion 494 provided on an extension of the second path RT42. A position of thecontact piece 51 when thecontact portion 515 is disposed at the position PT9 corresponds to the first position in the clockwise-side range. Movement in the +D direction of thecontact portion 515 having reached the position PT9 is restricted by the restrictingportion 494, and thus the rotation in the −D direction of therotator 42A is restricted. That is, the rotation of therotator 42A in the −D direction from the reference position is restricted by thecontact piece 51 being at the first position in the clockwise-side range. - When rotating force in the −D direction applied to the
rotator 42A is reduced by, for example, the user releasing his or her finger from theknob 43, in the state where thecontact piece 51 is located at the first position, thecontact portion 515 returns to the position PT1 owing to the biasing force in the −Z direction of the first biasingmember 52. As described above, the position of thecontact piece 51 when thecontact portion 515 is disposed at the position PT1 corresponds to the second position. This allows the relative movement in the +D direction of thecontact portion 515, and thus the rotation in the −D direction of therotator 42A that passes the reference position. - As described above, the
rotator 42A has a cylindrical cam structure in which the movement paths RT3 and RT4 are provided. The movement paths RT3 and RT4 each allow thecontact piece 51 to move in a direction along the rotation axis Rx when therotator 42A is rotated about the rotation axis Rx. - In the exemplary embodiment, the
path forming portion 491 that configures the second path RT32 and thepath forming portion 493 that configures the second path RT42 are not provided in the vicinity of the first position, and thus thecontact piece 51 is movable to the second position at a timing at which thecontact piece 51 reaches the first position. In therotary operator 2A according to the exemplary embodiment also, as with therotary operator 2 according to the first exemplary embodiment, it is possible to keep a balance regarding ease of movement of thecontact piece 51 from the first position to the second position. - For example, the
contact piece 51 has difficulty returning to the second position by, for example, increasing in the distance between the first position and the second position. - Further, the
contact piece 51 has difficulty returning to the second position by, for example, controlling a movement rate in the ±Z directions of thecontact piece 51 with use of a viscous lubricant or the like. - Effects of Second Exemplary Embodiment
- The acoustic device according to the exemplary embodiment described above has the same effects as those of the
acoustic device 1 according to the first exemplary embodiment. - That is, the acoustic device according to the exemplary embodiment includes the
rotary operator 2A. - The
rotary operator 2A includes therotator 42A and thecontact piece 51. The movement paths RT3 and RT4 inclined to the circumferential direction about the rotation axis Rx are provided for the outercircumferential surface 49A of therotator 42A. Therotator 42A is rotated about the rotation axis Rx. Thecontact piece 51 comes into contact with therotator 42A, and moves along the movement paths RT3 and RT4 in the direction along the rotation axis Rx in association with the rotation of therotator 42A. - In the counterclockwise-side range, the rotation of the
rotator 42A in the +D direction (the first rotation direction) about the rotation axis Rx is restricted by thecontact piece 51 being at the first position in the counterclockwise-side range when therotator 42A is rotated in the +D direction and reaches the reference position. The +D direction is the clockwise direction. - When the rotating force in the +D direction applied to the
rotator 42A is reduced in the state where the rotation of therotator 42A in the +D direction from the reference position is restricted, thecontact piece 51 returns to the second position, thereby allowing the rotation of therotator 42A in the +D direction from the reference position. - Further, in the clockwise-side range, the rotation of the
rotator 42A in the −D direction (the first rotation direction) about the rotation axis Rx is restricted by thecontact piece 51 being at the first position in the clockwise-side range when therotator 42A is rotated in the −D direction and reaches the reference position. The −D direction is the counterclockwise direction. - When the rotating force in the −D direction applied to the
rotator 42A is reduced in the state where the rotation of therotator 42A in the −D direction from the reference position is restricted, thecontact piece 51 returns to the second position, thereby allowing the rotation of therotator 42A in the −D direction from reference position. - With such a configuration, it is possible to restrict the
rotator 42A rotated in the +D direction from being erroneously rotated in the +D direction beyond the reference position. This makes it possible to easily rotate therotator 42A in the ±D directions in the rotation range (the counterclockwise-side range) from the reference position to the rotation limit in the −D direction. When therotator 42A rotated in the +D direction reaches the reference position, the rotating force in the +D direction applied to therotator 42A is reduced, whereby thecontact piece 51 returns to the second position and it is possible to rotate therotator 42A in the +D direction from the reference position. This makes it possible not only to restrict the rotation of therotator 42A in the +D direction from the reference position, but also to allow the rotation of therotator 42A in the +D direction from the reference position. - Similarly, it is possible to restrict the
rotator 42A rotated in the −D direction from being erroneously rotated in the −D direction beyond the reference position. This makes it possible to easily rotate therotator 42A in the ±D directions in the rotation range (the clockwise-side range) from the reference position to the rotation limit in the +D direction. When therotator 42A rotated in the −D direction reaches the reference position, the rotating force in the −D direction applied to therotator 42A is reduced, whereby thecontact piece 51 returns to the second position and it is possible to rotate therotator 42A in the −D direction from the reference position. This makes it possible not only to restrict the rotation of therotator 42A in the −D direction from the reference position, but also to allow the rotation of therotator 42A in the −D direction from the reference position. - Operability of the
rotary operator 2 is thus improved. - The disclosure is not limited to the above exemplary embodiments, and modifications and improvements within the scope of achieving the disclosure objects are included in the disclosure.

- A conclusion of the disclosure is described below.
- [1] A rotary operator includes: a rotator including a movement path provided for an outer circumferential surface and inclined to a circumferential direction about a rotation axis, the rotator being configured to rotate about the rotation axis; and a contact piece configured to come into contact with the rotator, and move along the movement path in a direction along the rotation axis in association with rotation of the rotator, in which rotation of the rotator in a first rotation direction about the rotation axis is restricted by the contact piece being at a first position when the rotator is rotated in the first rotation direction and reaches a predetermined position; and when rotating force in the first rotation direction applied to the rotator is reduced in a state where rotation of the rotator in the first rotation direction from the predetermined position is restricted, the contact piece returns to a second position to allow the rotation of the rotator in the first rotation direction from the predetermined position.
- With such a configuration, when the rotator rotated in the first rotation direction reaches the predetermined position, the rotation of the rotator in the first rotation direction is restricted at the predetermined position. According to this, it is possible to restrict the rotator from being erroneously rotated in the first rotation direction beyond the predetermined position. This makes it possible to easily rotate the rotator in the first rotation direction and in the direction opposite to the first rotation direction, in the rotation range from the predetermined position to the rotation limit in the direction opposite to the first rotation direction.
- When the rotator rotated in the first rotation direction reaches the predetermined position, the rotating force in the first rotation direction applied to the rotator is reduced, whereby the contact piece returns to the second position. This makes it possible to rotate the rotator in the first rotation direction from the predetermined position.
- Accordingly, it is possible not only to restrict the rotation in the first rotation direction from the predetermined position, but also to allow the rotation of the rotator in the first rotation direction from the predetermined position. Operability of the rotary operator is thus improved.
- [2] The rotary operator according to [1] may further include a first biasing member that biases the contact piece in a direction from the first position toward the second position.
- With such a configuration, the contact piece can easily return to the second position from the first position, when the rotating force in the first rotation direction applied to the rotator is reduced in the state where the rotation of the rotator in the first rotation direction from the predetermined position is restricted. It is therefore possible to easily perform the rotation of the rotator in the first rotation direction from the predetermined position, and to improve operability of the rotary operator.
- [3] In the rotary operator according to [1] or [2], the rotator may include a restricting portion that comes into contact with the contact piece when the rotator is rotated in the first rotation direction and reaches the first position, and restricts relative movement of the contact piece with respect to the rotator in a direction opposite to the first rotation direction.
- With such a configuration, it is possible to restrict the rotator, which has reached the predetermined position by being rotated in the first rotation direction, from further rotating in the first rotation direction by the contact piece coming into contact with the restricting portion. The first biasing member biases the contact piece in the direction from the first position toward the second position. Thus, when the above-described rotating force is reduced, the contact piece easily returns to the second position owing to the biasing force of the first biasing member.
- Operability of the rotary operator is thus improved.
- [4] In the rotary operator according to any one of [1] to [3], the movement path may include: a first path along which the contact piece moves relatively with respect to the rotator in the direction opposite to the first rotation direction from the second reference position, when the rotator is rotated in the first rotation direction from the predetermined position; and a second path by which the contact piece is led to the first position when the rotator having been rotated in the first rotation direction from the predetermined position is rotated in the direction opposite to the first rotation direction.
- With such a configuration, when the rotator rotated in the first rotation direction reaches the predetermined position in the state where the contact piece reaches the second path, it is possible to lead the contact piece to the first position. Accordingly, it is possible to restrict the rotator rotated in the first rotation direction from being rotated beyond the predetermined position.
- [5] In the rotary operator according to [4], a length of the first path in the first rotation direction may be shorter than a length of the second path in the first rotation direction.
- With such a configuration, it is possible to cause the contact portion to reach the second path from the first path with a small rotation amount of the rotator from the reference position. The second path is a path by which the contact piece is led to the first position. Thus, it is possible to locate the contact piece at the first position when the rotator reaches the predetermined position. Accordingly, it possible to restrict the rotation of the rotator that passes the predetermined position.
- [6] The rotary operator according to [4] or [5] may further include a second biasing member that biases the contact piece toward the rotation axis. The second path may be provided at a position closer to the rotation axis than the first path.
- With such a configuration, it is possible to prevent the contact piece that has moved from the first path to the second path from returning to the first path. Accordingly, it is possible to restrict the rotation of the rotator in the first rotation direction that passes the first reference position.
- [7] In the rotary operator according to any one of [1] to [6], the predetermined position may be a position where a length from the predetermined position to a rotation limit in the first rotation direction of the rotator is equal to a length from the predetermined position to a rotation limit in the direction opposite to the first rotation direction of the rotator.
- With such a configuration, the predetermined position is a middle position in the rotatable range of the rotator. This makes it possible to allow the rotatable range in the first rotation direction from the predetermined position and the rotatable range in the direction opposite to the first rotation direction from the predetermined position to be equal to each other. Usability of the rotary operator is thus improved.
- [8] An acoustic device includes the rotary operator according to any one of [1] to [7].
- With such a configuration, it is possible to achieve effects similar to those described above.
- [9] In the acoustic device according to [8], the rotary operator may configure an effect adjuster, the effect adjuster adjusting an effect amount of a first effect in accordance with a rotation angle of the rotator from the predetermined position toward the first rotation direction, and adjusting an effect amount of a second effect in accordance with a rotation angle of the rotator from the predetermined position toward the direction opposite to the first rotation direction.
- With such a configuration, for example, the rotation of the rotator in the first rotation direction that passes the first reference position is restricted, making it possible to prevent the effect amount of the first effect from being erroneously adjusted when the effect amount of the second effect is being adjusted. Usability of the acoustic device is thus improved.
